800 rooftops

Hawaiian Electric Companies – comprising Hawaiian Electric, Maui Electric, and Hawaii Electric – announced on April 12 that it would add capacity to its Customer Grid-Supply program to allow more rooftop systems to interconnect to the grid. Estimates show that at least 20 MW is available for customers of the three companies, representing about 2,800 private rooftop solar systems. More than half of that capacity is on Oahu.
